which would be better in my wife's 2003 2.7 4cyl toyota tacoma? i know analysis is the only way to know this, but what does everyone think?
i am a dealer and price is no object but i will try to do amsoil's recommended intervals w/ analysis.
so what's better their asl 5w30, hdd 5w30 or 0w30?
she does alot of short trips and mixed driving.
i am in new england and am currently using the 0w30
I run the 0w-30 in 2 Saab turbos, 1 Volvo turbo, and a Dodge 350 van. My kids run 0w-30 in 3 Volvos, 2 Saabs, 1 Subaru.
When the 0W-30 became available, years back, my son-in-law changed from AMSOIL 10w-30 to the 0W-30. Called me a couple months later to say he was getting 50-75 miles more per tankful before the red light came on telling him to get gas.
I move about as much 0w-30 as 5W-30 and 10W-30 combined (except to shops)
